This invention relates toarazor sharp-y ener in which a plurality ofrapidly revolv-l ing rolls which arel provided with abrad-m, ingsurfaces of rdifferent degrees of {ine-y ness, are employed. i

Among the objects of thisinvention are to obtain/razor Sharpeners of,thekind namedv which willform, together vwith the'` motive powertherefor, a single unit; to obtain a razor Sharpener which yissimple inconstruction, .isvdurabla andis not liable( to break or get out oforder; and an additional object is toqobtain a` razor sharpener of thekind named by means of which a razor blade may `readilyhe moved from.

a position in vwhich it may be opera-tedon by rolls having a givendegreelof abrading surface, torollsrof a different degree` `'of abradingsurface. A further Objectis ,to obtain a razor Sharpener of the kindnamed bymeans of whichA bothisides'otyaurazor blade adiacent'to thecutting edges thereof may easily be alternately applied to the abradingsurface of the rolls corresponding Vwith vthe positionof. -said .razorblade. An additional object is to obtain means for rmlyholding arazorblade ywhich is to be sharpened by the machine in such. po: s'itionthat when` said blade is presented to the abrading surfaces of saidrolls itwill be suitably positioned `to properly7 sharpen the same.

I have illustrated a machine embodying the inventionin .thedrawingreferred to, in which- A 1 y Y.

The4 standards B, B ,1 are,respectively, providedwith` a4 recess K, K', see Figs. 2 and 3; and L,AL,f respeotii'fely 'represent rods which servethedouble function oftie` rods between the standards, and guidesLfor the blade holder aboutto`loe described; y Rods L, L", respectively, lare rigidly held instandards B ,BQ by screws 'Z,Z, and Z-, Z. The? endsy ofLSaid ro'dsfareprovided'with apertures having. internal "screw threads correspondingwith the screw threads on said screws Z, Z, and Z', Z. The foregoingrecited manner of securing rods L, L' in standards B, B', is to enablethe operator to insert thehandle M in place on said rods L, L', bypassing it through said recesses K, K', in placing said handle on saidrods and removing it therefrom. The handle M comprises members which aresubstantially duplicates, and which are p-ivotally joined by rod or pinm, extending through abutments m', m'. m, m", represent abutments on theinner faces of the members of handle M, the opposing faces of saidabutments m", m" being bevelled, and N represents a lever which ispivota-lly mounted on pin n. The pivotally mounted end n and n of saidlever N being bevelled correspondingly with the abutments m", m", sothat the turning of said lever on its pivot n, will force the ends ofthe members of handle M where said lever N and vabutments m" fm," are'ositioned. a art with said abutments in conta-ct with said rods, asillustrated in Fig. 3, the cutting edge of said razor blade P will be insuitable relation with the surfaces of the several rolls, so that as thefree end of said handle M is moved up or down, turning said handle onone or the other of said rods L, L', the edge of 'the razorblade whichis, tov be sharpened, will be. brought in proper contact' with theabradingsurface of rolls corresponding with the position, laterally, ofsaid handle between said rods.

To operate the machine the motor X is energized, and the several rollsare rapidly revolved. The handle M, having a razor blade secured betweenthe jaws O, O, is in- Serted, as recited, between the rods L, L', and infront of the determined pairs of said rolls. The handle M, M, is turnedon said rods so as to alternately' bring said razor blade in Contactwith a lower and an upper one of said determined pair of rolls, and saidrazor blade is ground thereby.. When suitably lground by said determinedrolls the handle is turned to a neutral positiony and moved along saidrods L, L to proper position between the adjacent rolls, having a finerabrading surface. The operation last above described is con tinued,until the razor blade 1s in suitable position between the rolls havingthe leather finishing surface, to which surfaces it is thensubjeetQd,until operations on the blade mimos are completed, when said handle maybe removed from the machine, either by with drawing it directlytherefrom, or by coniniiled Sliding of the handle along the rods It isto be understood that the condition of a razor blade determines how manyof the several rolls are to be used to sharpen it, all of said rollsbeing required only when said blade is very dull.

I claim:

1. A razor Sharpener comprising standards respectively provided withrecesses on one side'thereof, a plurality of parallel rodsconnectinglsaid standards, parallel shafts rotatably mounted yin saidstandards, means to rotate said shafts in opposite directions, rollsarranged in pairs rigidly mounted on said shafts, abrading surfaces onsaid rolls, the abrading surfaces of each pair being substantially alikeand the abrading surfaces of different pairs being different, incombination with a handle provided with ja'ws at one end thereof adaptedto hold a razor blade, and abutments on the outer faces thereof, andsaid handle adaptedk to be placed between said rods with 'the razor insaid jaws in spaced relation with the abrading surfaces of the severalrolls, said parallel rods respectively arranged to alternately lformthe'fulcrums of vsaid handle and said abutments respectively'arranged toalternately co-act with said rods tof/,determine the position of saidhandles on Asaid fulcrums.
